Readily identified by the clustered spikes and reflexed 

 perigynia. 



Var. Hartii Gray. Slender; fertile spikes more or less dis- 

 tant, stalked, loosely flowered ; perigynia slightly reflexed. (C. 

 Hartii Dew) This is regarded by Prof. Britton as a distinct 

 species. 



128. Carex Tuckermani Dew. 



Stems l|°-3° high, stout, the acute angles rough ; leaves rough 

 l^"-2" wide, exceeding the culm; stiminate spikes 1-3, cylin- 

 drical, I'-H' long, on a stalk i'-V in length, the lowest some- 

 times with a few pistillate flowers at its base; pistillate spikes 

 2-4, densely flowered, oblong or cylindrical, ^'-J,' in length, 4:"-6" 

 thick, rather distant, the uppermost sessile, erect -spreading, the 

 remainder peduncled, the lowest sometimes remote and droop- 

 ing ; bracts leaf like, sheathless, longer than the culm ; perigynia 

 large, ovate, prominently nerved, thin, 4^"-b" long, 2|"-3" thick, 

 contracted into a slender bidentate beak, twice the length of the 

 lanceolate acute or pointed scale. 



Wet places in shaded stations or open fields-. Common. June, 

 July. 



The rather short thick spikes and the large ovate shining peri- 

 gynia are characteristic of this species. When very young the 

 perigynia of this species and of C. intumescens, C. Grayii and 

 some others with inflated perigynia are very pale or almost 

 white. 



129. Carex bullata Schk. 

 Stems l°-2° high, slender, erect, acutely angled, rough above, 

 smooth below the middle, dark purple and tibrillose at the base; 

 leaves smooth or roughish, stiff, mostly erect, l"-li" wide, about 

 the length of the culm ; staminate spikes 2-3, cylindrical or sub- 

 clavate, i -1^' in length on stalks Q"-9" long ; pistillate spikes 

 1-2, densely flowered, ii'-'d" (rarely 1') long, 3"-5" thick, sessfle 

 and erect, or, when 2, approximate or remote, the uppermost 

 short-stalked or sessile, the lowest on a slender peduncle 1' long 

 or less, erect or slightly spreading ; bracts leafy with obsolete 

 sheaths, usually exceeding the culm ; perigynia ovate, much in- 

 flated, nerved, thick, shining, widely divergent, tapering into a 

 long, smooth or minutely roughened, bidentate beak, longer than 

 the lanceolate acute or obtuse scale.
